Connects AI assistants directly to Prometheus metrics, enabling natural-language queries against monitoring data without writing PromQL.

Go-based MCP server for Prometheus and Mimir from Giant Swarm. Exposes 18 read-only tools wrapping the Prometheus HTTP API: instant and range PromQL queries, metric/label/series discovery, target and runtime info, TSDB stats, alerting rules, and exemplars. Can also run as a full OAuth 2.1 authorization server (backed by Dex/OIDC) that resolves each authenticated user's Mimir tenant IDs and enforces them on every query — built for multi-tenant, in-cluster deployments.

Usable rating — This tool is functional but has notable gaps. Review the evaluation notes below before deploying.

Why it matters

Connects AI assistants directly to Prometheus metrics, enabling natural-language queries against monitoring data without writing PromQL. Makes infrastructure health accessible to team members who are not metrics experts.

Best for

DevOps and SRE teams who want to query and interpret Prometheus monitoring data through AI without deep PromQL expertise.
